Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!

Can Nissan Pathfinder radiators be cleaned?

It could be a good idea to have your Nissan Pathfinder radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My Pathfinder overheated! What can cause that?

Your Nissan Pathfinder engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.

Why does the radiator in my Pathfinder sound like it’s rumbling or boiling?

Your Pathfinder’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!

Is rust in my Pathfinder radiator bad?

Yes. Rust in the radiator of your Nissan Pathfinder can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.

When to Service Your 1991 Nissan Pathfinder Cooling System

It can be tough to know when to have your Nissan Pathfinder radiator serviced if you don't know what it does, but it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Regular, proactive service on the radiator in your 1991 Nissan Pathfinder is a huge factor in the longevity of your engine. In fact, Nissan recommends replacing coolant/antifreeze at specific intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. Your radiator could be close to causing an engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Nissan Pathfinder Coolant Fluid Exchange

What’s included in a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Nissan Pathfinder’s cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. The water pump is one part on your 1991 Nissan Pathfinder engine that needs to be addressed ASAP once an issue is identified. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. If it’s not working well (or at all), your engine can easily overheat. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the heater core to the radiator cap, we’ll take excellent care of your 1991 Nissan Pathfinder at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
